Definitions
- the present invention generally relates to the field of blood bag systems, and specifically relates to the field of sterile docking multiple blood bag systems.
- Plastic bag systems for the collection, processing, and storage of blood and blood components are well known and have been used for thirty or more years.
- plastic films were used to make bags that ultimately replaced glass bottles
- many of the plastic blood bag systems were "open” in the sense that there existed the chance of contamination as blood or separated blood components were moved into or out of the system.
- the plastic bag system was a single bag having attached to it one or more tubings and ports for adding or removing bag contents.
- Blood bags most often are manufactured from plastics such as polyvinylester, polyvinyl acetates, polyolefin, polyvinylchloride homopolymer films, and the like. These materials tend to have a high water vapor transmission rate such that the bag has to be in an aluminum foil pouch to assure a longer shelf life of any solution contained in the bag. Not only do solutions contained within the bags become dehydrated, but the condensation on the outside of the bags resulting from the vapor transmission promotes bacteria growth.

Abstract
Description
- The present invention generally relates to the field of blood bag systems, and specifically relates to the field of sterile docking multiple blood bag systems.
- Plastic bag systems for the collection, processing, and storage of blood and blood components are well known and have been used for thirty or more years. In early embodiments, when plastic films were used to make bags that ultimately replaced glass bottles, many of the plastic blood bag systems were "open" in the sense that there existed the chance of contamination as blood or separated blood components were moved into or out of the system. Quite often, the plastic bag system was a single bag having attached to it one or more tubings and ports for adding or removing bag contents.
- As the use of various components and sub-components of blood became accepted, attempts were made to avoid potential contamination problems by providing multiple blood bags attached to each other by tubings and including valving systems. These multiple blood bag systems are known as "closed" in the sense that there no longer exists the chance of contamination after whole blood or a major component is introduced into and processed in the system.
- Depending on design, the number of bags, and such factors as valving systems and internal solutions, there now exists a variety of closed multiple blood bag systems. Available systems permit the collection, processing and storage of well known blood components such as red cell concentrates, plasma, and platelets.
- Blood bags most often are manufactured from plastics such as polyvinylester, polyvinyl acetates, polyolefin, polyvinylchloride homopolymer films, and the like. These materials tend to have a high water vapor transmission rate such that the bag has to be in an aluminum foil pouch to assure a longer shelf life of any solution contained in the bag. Not only do solutions contained within the bags become dehydrated, but the condensation on the outside of the bags resulting from the vapor transmission promotes bacteria growth.
- Existing blood bag systems frequently are packaged within aluminum foil pouches to reduce the amount of vapor transmission. Typically, blood bags are sterilized, placed inside an aluminum foil pouch, sealed, and then heat treated. However, to make a sterile docking to another system, the pouch must be opened to access the tubing contained within the bag. The combined blood bag systems then are repackaged in a single pouch for storage. Unfortunately, this method of docking multiple blood bag systems reduces the shelf life of the blood bag units. Furthermore, the possibility of mold growth in the blood bag system is increased due to the handling of the individual units and the necessary exposure of the individual systems to the environment.
- Thus, there remains a need for an apparatus for sterile docking multiple blood bag systems without exposing the systems to handling and environmental contamination.
- The present invention is an apparatus and method for sterile docking two or more
plastic bag units 110. The invention generally includes apouch 102 manufactured from an essentially vapor transmission resistant material. Contained within thepouch 102 is at least oneplastic bag unit 110 and a predetermined amount ofsterile tubing 108 connected thereto. - The
pouch 102 includes anaperture 104 in one wall or at one seam through which a tube fitting 106 protrudes. Preferably, thefitting 106 is sonic welded in place in theaperture 104 to form a hermetic seal. Thetube fitting 106 has an internal diameter sufficient to permit passage therethrough of thetubing 108 contained within thepouch 102 and connected to thebag unit 110 contained therein. The protrudingtubing 108 then may be used for docking withother bag units 110. - In a preferred form of the invention, the
plastic bags 110 are blood bags that form part of a blood bag system. More specifically, the plastic bag system is a blood bag system, having at least one blood bag unit and a amount of flexible tubing, and theplastic bag unit 110 is a blood bag unit that contains a solution including anticoagulant, saline, and the like for use in conjunction with collected blood. - FIGURE 1 is a perspective view of an embodiment of the present invention.
- FIGURE 2 is a front cutaway view of an embodiment of the present invention.
- FIGURE 3 is a detail cross-section of a fitting used in an embodiment of the present invention.
- FIGURE 4 is a perspective view of an exemplary configuration using an embodiment of the present invention.
- The present invention is a
system 100 for sterile dockingplastic bags 110 contained within a vapor transmission containment pouch. In a preferred form of the invention, thesystem 100 is used for sterile docking multipleblood bag units 110, at least one ofsuch units 110 being contained within theinventive system 100. - FIGURE 1 shows a perspective view of one embodiment of the
present system 100. In that illustrated embodiment, thesystem 100 includes apouch 102 of sufficient size and dimensions to hold a bag unit (110 of FIGURE 2). The illustratedpouch 102 is sealed at all edges such that the contents of the pouch are maintained in an air-tight environment. - Preferably, the
pouch 102 is manufactured from a material that may be sterilized, either by heat (e.g., autoclave), chemical, radiation, or other standard methods known and used in the art. The material preferably is vapor transmission resistant; that is, the material does not transmit water, in vapor form, to outside of the pouch from inside the pouch. Preferably, the moisture transmission value of the pouch material is zero or as close to zero as possible. In a preferred embodiment of the present invention, thepouch 102 is manufactured using an aluminum foil laminate, which has a known water transmission rate of zero. - One of the advantages of using aluminum foil as a pouch material is that it has the lowest water vapor transmission rate of other materials, it is low cost, and it is generally commercially available. In a preferred form of the invention, the
pouch 102 is constructed from a laminate that includes an outer layer of a polyester film, a middle layer of annealed aluminum foil, an inner layer of polyethyelene or polypropylene, and an intermediate tie layer of polyethylene copolymer of FDA approved adhesive. Alternatively, the intermediate tie layer may be an extrusion laminated seal layer. Foil material is commercially available from several suppliers, including American National Co., Mt. Vernon, Ohio. - The
inventive system 100 further includes anaperture 104 or other opening in thepouch 102 through which a tube fitting 106 protrudes. Theaperture 104 may be located either in one of the walls of the pouch 102 (as illustrated in FIGURE 1), or may be formed at one of thepouch 102 seams. In a preferred embodiment, theaperture 104 is positioned in one of thepouch 102 walls and proximal one end of thepouch 102. The position of theaperture 104 may depend on such variables as the position of thebag unit 110 within thepouch 102, the amount oftubing 108 to be threaded through thefitting 106, and other manufacturing and assembly considerations. - The
plastic bag unit 110 contained within thepouch 102 preferably is sterilizable. Standard sterilizing methods, such as heat, chemical, radiation, and the like, may be used on thebag units 110 prior to insertion of thebag units 110 inside thepouch 102. Presterilization of thebag units 110 may further extend the shelf-life of thebag 110 contents. - Turning now to FIGURE 2, that shows a front cutaway view of the
present system 100. In that illustrated embodiment, thesystem 100 includes aplastic bag 110 contained within thepouch 102. Theplastic bag 110 may be a blood bag, manufactured from standard materials used in the blood bag industry.Such bags 110 are commercially available from Miles Inc., Covina, California. Thebag 110 may contain a solution for transfer to anothersystem 100, a blood collection system, another plastic bag, and the like. The present invention is particularly suited for sterile docking of theplastic bag 110 to another sterile system. - The
bag 110 of the illustrated system may include aport 112, attached to thebag 110, that has an attached amount oftubing 108 that extends from the contents of thebag 110 to outside thesystem 100. A standardfrangible valve 120 may be positioned within the port to control flow of fluid from thebag 110 to outside of thesystem 100 via thetubing 108. - In the illustrated embodiment, a
bushing 114 is attached to thebag port 112 and extends at least partially through theaperture 104. Thebushing 114 may extend beyond the fitting 106, and acts as a conduit for thetubing 108. In an alternative embodiment of the invention, thetubing 108 extends directly from thebag 110 through the fitting 106 without the guidance of abushing 114. - In a preferred embodiment of the invention, and as shown in detail in FIGURE 3, the tubing fitting 106 includes a
main body portion 116 and afoot portion 118. In assembling the illustrated embodiment of the invention, thefitting body 116 is inserted through theaperture 104 from the inside of thepouch 102 such that thebody 116 protrudes from within thepouch 102 and thefoot portion 118 abuts against the inner pouch surface adjacent theaperture 104. The fitting 106 may then be welded or otherwise attached to thepouch 102. - In the illustrated embodiment, the
fitting body 116 includes a pair offlanges 120 that extend around the circumference of the inner side of thebody 116. The flanges function to grip thebushing 114, ortubing 108 when nobushing 114 is present, to further secure thebushing 114 ortubing 108 in position within the fitting 106. - In a preferred form of the invention, the fitting 106 is sonically welded to the
pouch 102 to form a hermetic seal. In alternative forms of the invention, the fitting 106 is attached within theaperture 104 by chemical, RF, or other methods known and available to those skilled in the art, Preferably, any method that produces a hermetic seal may be used to secure the fitting 106 to thepouch 102. - In one embodiment of the present invention, the terminal end of
tubing 108 that extends outside of thepouch 102 is sealed. Preferably, the seal is an IRE seal, but the manner and type of seal may depend on the specific materials from which the tubing is manufactured. It is desirable that the terminal end of thetubing 108 be sealed or otherwise closed to prevent uncontrolled loss of solution from thebag 110 and to prevent introduction of contaminants into thebag 110. - In practicing the present invention, and referring to FIGURE 4, the portion of the
tubing 108 that extends outside of thepouch 102 is connected totubing 132 from anothersystem 130. Thesystem 130 may include a blood bag system, as illustrated in FIGURE 4, another singleblood bag unit 110 similar to that shown in FIGURE 2, or the like. In a preferred method of practicing the present invention, sterile docking is accomplished using a sterile docking device, such as that commercially available from DuPont, Wilmington, Delaware. Using that exemplary device, the twotubings system 100 is sterile docked, thefrangible valve 112, if present, may be opened to permit fluid flow from thebag 110 to the sterile dockedsystem 130. That device is described in further detail in U.S. Patent No. 4,507,119, the relevant portions of which are incorporated herein by reference. Another sterile docking device is described in U.S. Patent No. 4,157,123, and which relevant portions thereof also are incorporated herein by reference. - In one embodiment of the present invention, a single
blood bag unit 110 is sealed within thepouch 102. In alternative embodiments, thepouch 102 includes two or more bags, each of which may be interconnected via tubing, or may have separate lengths of tubing extending outside of thepouch 102.
